[导入]NVelocity 模版引擎

今天用了一下 NVelocity, 感觉还不错， 虽然最后的release 版 是2003年的， 但和vs 2008 以及范型等兼容性没有问题。
Write a Simple sample：

Template：

Cool,
this is a Velocity Template

let's get start:

## this is comments

#set($user="jimmy")

hello $user!!!!! 


$fruits

the gameName is: $game1.GameName

#foreach ($fruit in $fruits)

!!! I Like $fruit 


#end

.NET
Code：

 public class Game
{ public string GameName{get;set;} public string GameType{get;set;} public int Year{get;set;}
} private void btnRender_Click(object sender,
EventArgs e) { //tbTemplate.Text; Velocity.Init("nvelocity.properties");
VelocityContext context = new VelocityContext();
Game game1 = new Game
{ GameName = "DOOM",
GameType = "FST",
Year = 1990
}; context.Put("name", "Velocity");
context.Put("project", "Jakarta");
context.Put("game1",
game1); List<String> strList = new List<String>();
strList.Add("Apple");
strList.Add("Orange");
strList.Add("Banana");
context.Put("fruits",
strList); //Template
template = new Template(); StringWriter writer = new StringWriter();
Velocity.Evaluate(context, writer, "string1",
tbTemplate.Text); tbResult.Text = writer.ToString();
}

Output:

Cool,
this is a Velocity Template

let's get start:

hello jimmy!!!!! 


System.Collections.Generic.List`1[System.String]

the gameName is: DOOM

!!! I Like Apple 


!!! I Like Orange 


!!! I Like Banana 

若从源码编译： 几点需要注意

1) 它所用的log4net 版本比较老, 可能有兼容性问题

2) directive.properties 和 nvelocity.properties 两个文件需要设成 Embedded Resource
